Steel CPM 3V Annealed vs CPM 3V HT 60-62 HRC
Steel · CPM 3V temper comparison
CPM 3V Annealed and CPM 3V HT 60-62 HRC are two conditions of the same steel grade, CPM 3V: Annealed versus HT 60-62 HRC (high-hardness temper). The chemistry is identical, so every difference below comes from the condition. CPM 3V HT 60-62 HRC is the stronger of the two: yield strength 2,050 MPa (297 ksi) against 600 MPa (87 ksi) for CPM 3V Annealed, about 3.4 times as much; tensile strength follows at 2,400 MPa (348 ksi) vs 900 MPa (131 ksi). In exchange, CPM 3V Annealed is the more ductile: elongation 12% versus 1.5% for CPM 3V HT 60-62 HRC, and CPM 3V HT 60-62 HRC is harder (640 HB vs 255 HB). CPM 3V Annealed runs hotter in service (400°C vs 200°C continuous). On the shop floor, CPM 3V Annealed machines more easily (poor vs not recommended) and CPM 3V Annealed welds better (poor vs not recommended).

CPM 3V Annealed vs CPM 3V HT 60-62 HRC: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

CPM 3V Annealed vs CPM 3V HT 60-62 HRC — frequently asked
Is CPM 3V HT 60-62 HRC stronger than CPM 3V Annealed?
Yes. CPM 3V HT 60-62 HRC has a typical yield strength of 2,050 MPa (297 ksi) against 600 MPa (87 ksi) for CPM 3V Annealed — about 3.4 times as much. Tensile strength is 2,400 MPa (348 ksi) vs 900 MPa (131 ksi).
Which condition does FabDigit quote by default, Annealed or HT 60-62 HRC?
Annealed is the default CPM 3V condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, CPM 3V Annealed or CPM 3V HT 60-62 HRC?
CPM 3V Annealed. Its machinability rates poor (30/100) against not recommended (5/100) for CPM 3V HT 60-62 HRC; for welding the order is CPM 3V Annealed first (poor, 25/100) then CPM 3V HT 60-62 HRC (not recommended, 5/100).
